IVAN USOHAKOFF, OF Zinc, FINLAND.

CARD-EXHIBITOR.

SPECIFICATION forming part of Letters Patent No. 613,339, dated November 1, 1898.

Application filed July 30, 1896. serial No. 601,095- (No model.)

To aZZ whom it may concern.-

Be it known that I,lvAN IISOHAKOFF, lector, of 5 Ryska Kyrkogatan, Abo, Finland, in the Empire of Russia, have invented new and useful Improvements in Card-Exhibitors, (for which I have obtained a patent in Germany, No. 91,114, bearing date March 25, 1896,) of

- which the following is a specification.

The object of the present invention is to provide a holder for geographical maps and the like which shall preserve the map from wear and also permit of easy inspection of the same.

On the accompanying drawings the holder is represented.

Figure 1 is an elevation of the opened holder. Fig. 2 shows an elevation of the mechanism. Fig. 3 is a section on line a: 00 of Fig. 2 on a greater scale.

The holder consists,essentially, of the frames or bars a and b, each having an eye 01 e secured to it and being fitted to slide upon guide-rods f and g, respectively. The guiderods are bent at their ends, and these ends are connected by means of a plate It. Between the guide-rods f and g a frame or bar 0 is fixed, and that vertically to the plate h. Each of these three bars a, b, and 0 serves to carry one portion of the map or card,which has been previously divided by horizontal sections in three portions Z, Z and Z. The bar a has fixed to it the upper portion Z, the bar 0 the middle portion l and the bar I) the lower portion Z, of the map or card.

In using the holder the upper portion Z of the card, yet folded, is pushed upward by sliding the eye dof its bar 0. upon the guiderod f. Then the bar I), provided with the portion Z of the card, yet folded, is pushed downward by sliding its eye 6 upon the guide-rod g. The middle portion Z of the card remains in its position and the three portions of the card are displayed. The portions of the card lie now in such a position that the card is ready for use. In Fig. l the upper and the middle portion Z and Z are yet folded, while the lower portion 1 is displayed. After using the card the portions are folded together and the rods a and I) pushed back into their normal position.

For the better preservation of the map or card a cover 2', Fig. 1, may be provided.

The improved holder presents these advantages, that the necessity for folding the card in cross directions is avoided, and also that any one portion of or the entire map or card may be exposed for inspection.

When designed for use with smaller maps or cards, one of the frames or bars is omitted, so thatthe holder has one fast and one sliding frame only.

Having now described my invention, what I claim, and desire to secure by Letters Pat'- ent, is-- 1. In a holder for maps, cards and the like,

the combination of a fixed frame or bar, with guide-rods carried by said frame or bar, one or more frames or bars, each provided with an eye fitted to slide on one of the guide-rods, a map or card divided into sections, one of said sections attached to each frame and so arranged that when said frames are pushed outwardly the sections will be brought into position to display the map as a whole, substantially as and for the purpose set forth.

7 2. In a holder for maps, cards and the like, the combination of a plate, with a frame or bar fixed to the said plate, guide-rods attached to, the said plate, one or more frames or bars, each provided with an eye fitted to slide on one of the guide-rods, a map or card divided into sections, one of said sections attached to each frame and so arranged that when said frames are pushed outwardly the sections will be brought into position to display the map as a whole, substantially as and for the purpose set forth.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.

IVAN USOI-IAKOFF.
